Rockwell Automation 2706-DXX Dataliner Message Display DL5 Series - Manual (Page 12)

2706-UM001A-US-P
1-2 Introduction to the DL5
Main Features Serial or Parallel Triggering - Stored messages can be triggered by
sending messages to the DL5 serial or parallel ports. Both the serial and
parallel ports cannot be used at the same time. The Serial Trigger/
Configure DIP switch (SW1-1) on the back of the DL5 determines which
port is used for triggering.
DC Input - The parallel port of the DL5 accepts 5-24 volts DC. DL5s are
powered by 12-24 volts DC.
Round Robin Mode - The round robin mode allows you to replace up to
sixteen pilot lights, that are being used as status indicators, with a single
DL5 display. Instead of your control system turning on a pilot light, it will
trigger a message for display.
Priority Mode - The priority mode is similar to the round robin mode.
However, the priority mode has an additional feature that allows you to
designate certain messages as more important than other messages. If two
or more messages are triggered at the same time, only the priority message
will be displayed.
Numeric Mode - The numeric mode allows you to use the DL5 as a
numeric only 3 or 4 digit (BCD) display. Your control system can transmit
real time binary coded decimal (BCD) data to the DL5 for immediate
display. Use the DL5 to display numbers as large as
999, 999, 999, 999, 999.
Binary or BCD Input Mode - Your control system can transmit data and
message triggers in either binary or Binary Coded Decimal (BCD) formats.
This allows the recall of up to:
•
94 messages with a one or two line 2K byte DL5
•
387 messages with a two line 8K byte DL5
Debug Mode - You can verify the operation of the program in a host
programmable controller (PLC) using the debug function of the DL5. The
debug mode will display the condition (ON or OFF) of the sixteen parallel
port data lines.
Note: Special application considerations may be necessary for some types
of controlling devices. Refer to Chapter 8 for more details.
